Over the course of 40 years, photographer Sebastião Salgado has borne witness to the plights of marginalized communities the world over, from famines to civil wars to unsafe labor conditions. Now he turns his camera toward another subject under threat – our natural world – framing pristine landscapes and bounties of biodiversity within a huge project celebrating the environment.

Directed by Wim Wenders and Juliano Ribeiro Salgado.
